Gree YAG-remote suppport

[samuliHeikkinen]

Hey!

I've been trying to add support for the Gree Amber/Nordic with the YAG remote. So far I've been able to decode most of the ir signals and they are pretty close to YAC model. With some light mods the YAC decoder is able to detect everything else than I-FEEL temperature from the signals.

There is one big difference though. The signal sent by YAG remote is always 24 bytes (213 pulses). There is also some advanced features which send which 32 bytes. I tried implementing the sending the signals but what I can see the YAG needs a send()-function which is pretty much different from the others as the structure of the payload is a lot different.

I've attached a sample of the decoding.

Any tips on where to go from here?

Some time ago I made some changes to support the Gree YAP model. It is not really ready to merge back with the mainline yet but it does look pretty much similar to your output for the YAG

Perhaps you can give it a go... https://github.com/thoutenbos/arduino-heatpumpir/commit/4addf28e57526b4dbcdddc560c3002420e68cd6c

@samuliHeikkinen @thoutenbos

I also have a YAG remote and i would like to use ifeel function. Any idea how to solve this thing?

I will able to help data or similar if you need.

@vampywiz17 you could try my branch to see if it works for you on YAG
